Description

Technical Field

[0001] This application belongs to the field of special insulating joints for gas, and particularly relates to a special insulating joint for gas. Background Art

[0002] When connecting a gas pipeline to a gas valve or a gas stove, a gas hose is used. Existing gas hoses are all flame-retardant PVC hoses, and good sealing and firmness are required during connection.

[0003] The existing publication number CN220540568U discloses a conversion joint for a gas hose, which includes a body with a first connection end. A locking nut is threadedly connected to the outside of the first connection end, and a sealing washer that can be squeezed when the locking nut is tightened is provided between the end of the first connection end and the locking nut. The body is in a right-angled shape, and the body also has a second connection end with an external thread. Both sides of the body at the bending position have clamping planes, and the two clamping planes are parallel to each other.

[0004] Although the above conversion joint has advantages such as convenient connection and reliable structure, the part used to connect to the gas pipe is prone to being knocked and worn during idle storage. The wear of the part of the joint used to connect to the gas pipe will cause the joint to loosen when connecting to the gas pipe, resulting in gas leakage and potential safety hazards. Utility Model Content

[0005] The purpose of this application is to address the above-mentioned existing technical problems by providing a special insulating joint for gas, which can prevent the part of the insulating joint used to connect to the gas pipe from being knocked during idle storage of the insulating joint, provide protection for the part of the insulating joint used to connect to the gas pipe, make the connection relationship between the insulating joint and the gas pipe more stable, and the structure more reliable.

[0006] This application provides a special insulating joint for gas, including a joint body, and further including:

[0007] An outer pipe body, which is installed on the joint body;

[0008] A first installation joint, which is installed on the joint body, and the first installation joint is provided with a first external thread;

[0009] A second installation joint, which is installed on the joint body, and the second installation joint is provided with a first internal thread;

[0010] A sealing ring, which is installed on the joint body;

[0011] An installation component, which is installed on the joint body;

[0012] A protection component, which is installed on the first installation joint and the second installation joint;

[0013] Among them, the protection component includes a first protective sleeve, a second internal thread, a second protective sleeve, and a clamping block. The inner wall of the first protective sleeve is provided with a thread, and the thread on the first protective sleeve matches the first external thread on the first installation joint. The first protective sleeve is installed on the first installation joint through thread matching. The second protective sleeve is provided with a plurality of clamping blocks, and the clamping blocks and the second protective sleeve are integrally formed. The second protective sleeve is inserted into the second installation joint, and the clamping blocks abut against the inner wall of the second installation joint.

[0014] When the insulating joint is idle and stored, the first protective sleeve can be installed on the first external thread on the first installation joint through the second internal thread. The first protective sleeve is made of plastic. Insert the second protective sleeve into the second installation joint. When the second protective sleeve is inserted into the second installation joint, the clamping blocks are also inserted into the second installation joint and abut against the inner wall of the second installation joint to prevent the second protective sleeve from loosening and falling off. When the gas joint is needed, the first protective sleeve can be screwed out from the first installation joint, and the second protective sleeve can be pulled out from the second installation head. At this time, the user can connect and install the gas pipe through the first external thread on the first installation joint and the first internal thread on the second installation joint. The first protective sleeve and the second protective sleeve can prevent the part of the insulating joint connected to the gas pipe from being knocked when the insulating joint is idle and stored, provide protection for the part of the insulating joint used to connect to the gas pipe, make the connection relationship between the insulating joint and the gas pipe more stable, and the structure more reliable.

[0015] Furthermore, a pulling block is provided on the second protective sleeve.

[0016] Due to the pulling block provided on the second protective sleeve, the pulling block is integrally designed with the second protective sleeve, and the pulling block is made of soft plastic and has good deformation ability. When the user needs to pull out the second protective sleeve, the pulling block can be pulled to drive the second protective sleeve to disengage from the second installation joint. The pulling block makes it more convenient and efficient to pull out the second protective sleeve when the insulating joint is needed.

[0017] Furthermore, the outer tube body is a column with an outer hexagonal cross-section, and the outer tube body is integrally designed with the joint body.

[0018] Since the outer tube body is a column with an outer hexagonal cross-section and the outer tube body is integrally designed with the joint body, the outer tube body being a column with an outer hexagonal cross-section makes it less likely for the user to drop the insulating joint during installation, and at the same time makes it more convenient and labor-saving for the user to rotate and install the insulating joint.

[0019] Furthermore, the joint body further includes:

[0020] Limit grooves, a plurality of limit grooves are provided, and the limit grooves are provided on the joint body;

[0021] The limiting block is installed on the first installation joint and the second installation joint. There are several limiting blocks, and the limiting blocks can be inserted and pulled out in cooperation with the limiting grooves.

[0022] The joint body further includes limiting grooves and limiting blocks. The limiting grooves are arranged on two end faces of the joint body. There are several limiting grooves. The limiting blocks are installed on the first installation joint and the second installation joint. There are several limiting blocks. The several limiting blocks are distributed around the axes of the first installation joint and the second installation joint. The limiting blocks can be inserted and pulled out in cooperation with the limiting grooves, making it more difficult for the first installation joint and the second installation joint to break away from the joint body. At the same time, it avoids the first installation joint and the second installation joint from rotating when the user rotates and twists the outer pipe body or the gas pipe to fix the gas pipe and the insulating joint in a threaded manner. The cooperation of the limiting grooves and the limiting blocks makes it more stable for the user to connect and install the insulating joint and the gas pipe.

[0023] Furthermore, the installation assembly includes:

[0024] An installation groove, which is arranged on the joint body;

[0025] A second external thread, which is arranged on the installation groove;

[0026] An auxiliary installation outer sleeve, which is provided with an internal thread. The auxiliary installation outer sleeve can be installed on the installation groove by the cooperation of the internal thread and the second external thread. The auxiliary installation outer sleeve is provided with through holes;

[0027] Several limiting telescopic rods, which are installed on the auxiliary installation outer sleeve;

[0028] A fastening block, which is installed at the output end of the limiting telescopic rod;

[0029] A fixed cylinder, which is installed on the auxiliary installation outer sleeve. The fixed cylinder is provided with an internal thread;

[0030] A moving rod, which is provided with an external thread. The moving rod is installed in a threaded manner with the fixed cylinder. One end of the moving rod is rotatably connected to the fastening block;

[0031] A turning handle, which is installed on the moving rod.

[0032] There are two sets of the fixed cylinder, the movable rod, the fixed cylinder and the limit telescopic rod. After the gas pipe is installed on the gas connector, the user installs it on the second external thread of the installation groove through the internal thread on the auxiliary installation outer sleeve. Then the user drives the rotary handle to rotate. The rotation of the rotary handle drives the rotation of the movable rod. Since the external thread of the movable rod is matched with the internal thread in the fixed cylinder, the movable rod will rise or fall when it rotates. When it is necessary to fasten the position of the gas pipe, the user drives the movable rod to move downward to drive the fastening block to move downward. At this time, the two corresponding fastening blocks move closer to each other until they abut against the gas pipe to fasten the gas pipe. The installation component makes the gas pipe more difficult to loosen and has better stability after installation.

[0033] Furthermore, the rotary handle is provided with friction lines.

[0034] With the friction lines provided on the rotary handle, the friction lines can increase the friction between the user and the rotary handle when the user operates and rotates the rotary handle, making it easier for the user to rotate the rotary handle, and at the same time, the friction lines make it less likely for the user to let go of the rotary handle during operation.

[0035] The beneficial effects of this application are as follows:

[0036] 1. The first protective sleeve and the second protective sleeve can prevent the part of the insulating joint connected to the gas pipe from being knocked during the idle storage of the insulating joint, provide protection for the part of the insulating joint used to connect with the gas pipe, make the connection relationship between the insulating joint and the gas pipe more stable, and the structure more reliable;

[0037] 2. When the user needs to pull out the second protective sleeve, the pulling block can be pulled to drive the second protective sleeve to disengage from the second installation joint. The pulling block makes it more convenient and efficient to pull out the second protective sleeve when the insulating joint is needed;

[0038] 3. The outer pipe body is a column with an outer hexagonal cross-section, which makes it less likely for the user to let go of the insulating joint during installation, and at the same time makes it more convenient and labor-saving for the user to rotate and install the insulating joint.
